Defender for Linux can be tricked into executing arbitrary code as root. Writeup: https://astr.al/notes/2024-11-28_mdatp_privesc

@astraleureka nice work! If I may ask… did they award you a bounty for this bug?
@raptor ha. from MS for a Linux product? no chance. I got 40 points on their ~leaderboards~. :eyeroll:
@astraleureka yeah thought so 😞
